Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0052]TDOA is a positioning method using time difference. By comparing the absolute time difference between the data packets sent by the device to be positioned and arriving at each positioning base station, a hyperbola with each positioning base station as the focus and the distance difference as the long axis can be drawn. The intersection point of the hyperbola is the position of the device.

[0053] In an ideal open environment, the TDOA algorithm can obtain higher precision. However, in an occluded environment, the positioning accuracy of TDOA cannot be effectively g...

Abstract

The invention relates to an equipment positioning method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a first time difference of positioningdata packets sent by target equipment to be positioned and received by a master positioning base station and a first slave positioning base station in a positioning base station system, wherein the positioning base station system comprises the master positioning base station and at least two slave positioning base stations; based on the first time difference and the historical time difference, the numerical value fluctuation amplitude of the first time difference relative to the historical time difference is determined, and the historical time difference is the time difference when the main positioning base station and the first slave positioning base station receive historical positioning data packets sent by the target equipment in the historical time period; if the numerical fluctuation amplitude is greater than the abnormal fluctuation threshold value, indicating the master positioning base station and the first slave positioning base station to measure and report the distance between the master positioning base station and the target equipment; and positioning the target device based on the reported measurement result. By adopting the method, the positioning precision of thetarget equipment can be improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a device positioning method, device, computer device and storage medium. Background technique [0002] With the development of information technology and wireless communication technology, positioning technology has important applications in personnel positioning, online travel, fire rescue, and Internet of Things. [0003] At present, a TDOA (Time Difference of Arrival, Time Difference of Arrival) positioning technology is generally used to realize device positioning. TDOA is a method of positioning using time difference. The TDOA algorithm determines the position of the device by detecting the time difference between the signals sent by the device and arriving at each base station. [0004] However, in the above method of locating the device through the TDOA algorithm, the device locating accuracy is low. Contents of the invention [0005] Based...
